Application October 21,

2 Claims.

This invention appertains to new and useful improvements in seals and more particularly to means wherebs the usual closure or gate'of a coal truck chute can be sealed in a practical manner.

The principalobject of the present invention is to provide a seal for coal truck chute gates which will permit the gate tobe sealed in a manner preventing unauthorized lifting of the gate without affording detection. I

Another important object of the invention. is to provide a seal of the character stated which can be installed on present-day types of chute Figure 1 represents a fragmentary rear elevational viewof a truck showing the chute and novel seal means.

Figure 2 is a sectional'view taken substantially on the line 2-2 of Figure 1;. I 1

Figure 3 is a perspective View of the lower bracket. i g

Figure 4 is a perspective view of the upper bracket.

,' Figure 5 is a perspective view of the pin.

Figure 6 is a fragmentary detailed sectional View on the line 3&6 of Figure 1.

Figure 7 is a rear elevation of the gate and modified form of latch means.

Figure 8 is a fragmentary perspective view of the latch arm shown in Figure '7. I

Referring to the drawings wherein like nu .merals designate like parts, it can be seen that numeral 5 represents the rear wall of a coal truck which has the vertically extending guides 6-45 for the chute gate 1. Numeral 8 denotes the chute which extends rearwardly from the truck and which has the vertically extending side walls 9 and ID.

In carrying out the present invention, a lower bracket A and an upper bracket B are employed and are shown in Figures 3 ands, respectively.

The lower bracket A is L-shaped having the portion a apertured to receive securing means for attaching the bracket to the wall 9. This bracket A includes the right angularly disposed elongated portion b on whichis the slider 43 which is provided with the horizontally disposed flange I i terminating in the longitudinally extending barrel !5 through which the pin. it is slidably disposed. The free end of the portion 2) 1938, Serial No. 236,356 (01. 298-7) 1 is bent backwardly to form the abutment or stop H for the slider l3.

Character reference B represents the upper bracket which has openings therein for receiving securing means I9 securing the bracket to the gate 1. The lower portion of this bracket B is bent outwardly to form the flange 20 which terminates in the barrel 2!. i

The relationship of the bracket B with respect to the bracket A is such as to result in the alignment of the barrel2i with the barrel [5 when the flange 20 comes down to rest upon the elongated portion 1) of the bracket A. With the barrels 2 and I5 thus aligned, the pin I 6 can be disposed therethrough. The pin it has the head 22 at one end and adjacent this head 22 are the longitudinally spaced openings 23. At the other end portion of the pin [6 is the third opening 24. A tie wire or the like 25 can be trained through the opening 26 and through one of the openings 23 so that the ends of this wire 25 are disposed out in front of the bracket [2 where a seal button 26 can be pressed in place, uniting the terminals of the wire 25.

Thus persons either authorized or unauthorized must break the wire 25 before the pin Hi can be removed to permit elevation of the gate 17 and discharge of the coal from the truck.

With this seal in place the purchasing consumer can. inspect the gate to determine whether the same has been ruptured preparatory to accepting the delivery.

A modified form of the invention is shown in Figure 7 wherein reference character 50; represents the rear of the coal truck on which arethe vertical guides Sci-43a in which the gate 111 is slidable. The short chute is denoted by reference character 8a and includes the side walls 9a and Mia. The upper bracket IBa is of the same construction as the bracket i8 and the slider |3a isof the same construction as the slider l3. The pin Hia is used in the same capacity as the pin iii in conjunction with the tie wire 25a and the seal 26a.

The modification resides solely in the lower bracket A and in the modification the bracket is denoted by reference character 52c. This bracket is divided into the plate section a and i the arm b. The adjacent ends of the plated and the arm b are provided with barrels 21 and 28, respectively. These barrels are aligned and have the pin 29 extending therethrough. Thus the arm I) and the plate a are hingedly connected together and rivets or the like'can be disposed through openings it in the plate a to secure the plate in position on the wall 9a. It can now be seen that when the gate 7a. is opened the arm I) can be swung to a position against the wall 9a so that it will not interfere with the discharge of coal.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter. Y

Having described the claimed as new is: v

1. In combination a dump truck body having a rearwai'dly disposed chute including sidewalls,

invention, what is a gate at the rear of the truck body ccinplementary tothe chute and being vertically'slidabie, an arm projecting inwardly fromjthe side wall of the chute, a slider on the arm provided with a horizontal barrel, a bracket on the end gate provided with a barrel adapted to be located in alignment with the barrel on the slider when the end gate is in closed position, and a pin for disposition through the aligned barrels.

2. In combination a dump truck body having a rearwardly disposed chute including side walls,

' alignment with the barrel on the slider when the end gate is in closed position, and a pin for disposition through the aligned barrels, and a hinged connection between the arm and the said sidewall of the chute.
